This study aims to evaluate the accuracy and clinical applicability of the iSelfie Heart Health software for blood pressure estimation.
Single-arm observational study at a hypertension clinic in Brazil with 641 participants.
Blood pressure measured using hospital-grade devices followed by facial video data collection using iSelfie rPPG.
Calibration utilized an individual linear regression model based on initial paired measurements.
In calibrated mode, rPPG estimates showed better agreement with SOC measurements than uncalibrated data.
Sensitivity for hypertension detection was 84.6%, and specificity was 93.4%.
Demonstrated potential for use in ambulatory and home monitoring.

Sebba-Barroso et al. (2026) studied this question.
